HOSE-COUPLING.

Specification of Letters Patent.

Patented Dec. 12, 1,911.

To all whom 'lt may concern:

Be 1t known that we, RAYMOND H. UTz and 'HERMAN F. GRAHL, ,citizens of the United States, serving in the United States Navy on the U. S. S. Cleveland, have invented a new' 'and useful Improvement in Hose-Couplings, of which the following is a specification.

This invention relates to hose couplings, and more particularly to detachable hose couplings, the ob]l ect beingto provide a hose coupling which is so constructed that it can be easily and quickly coupled and uncoupled.

Another obj ect of our invention is to provide a'hose coupling which is formed of a male and female member adapted to be locked together in such a manner that all danger of the members becoming separated accidentally is prevented.

A further object of the invention is to provide the female member with bayonet slots in which are adapted to lit lugs carried by the male member, said lugs being locked therein by a spring actuated'sleeve carrying oppositely disposed lugs which are normally held in the path of the lugs of the' female member so that after they are once in position it will bel impossible for the same to move without moving the spring actuated sleeve.

Another object of our invention is to provide a locking nut in connection with the device whereby the movement of the spring actuated sleeve can be controlled.

A still further object of the invention is to provide the conical socket of the female member with a rubber washer which is so mounted that it can be easily and quickly attached or detached so that when the same becomes worn, it can be readily replaced.

Still another object of our invention is to provide the male member with a detachable neck having a conical end adapted to t within the conical socket ofthe female member against the rubber washer, said neck being so mounted that it can be easily an'd quickly detached when desired.

With these various objects in view, our 1nvention consists in the novel features of construction, arrangement and combination of parts hereinafter fully described, vpointed out in the claims, and shown in the accompanying drawings, in which:

Figure 1 is a top planv view of our 1mproved coupler, partly broken away to show theposition of the lugs within the slot when in a locked position. Fig. 2 is a longitudinal sectional view. Fig. 3 is a section taken on the line 3-.3 of Fig. 2. Fig. 4 is a perspective viewI of the female member, the spring sleeve and lock nut being removed. Fig. 5 1s aperspective view of the male member. Fig. 6 is a perspective View of the spring actuated sleeve carrying the lugs, and Fig. 7 is a perspective view of the locking nut.

Referring to the drawings A indicates a female member and B a male member, each of which is provided vwith a threaded bore to which the 'respective ends of the hose to be coupled are adapted to be connected in the ordinary manner. lllhe female member A is provided with a socket A terminating in Va sleeve portion A2 which is provided with oppositely disposed longitudinal slots A3 having notched walls A* forming substantially bayonet shaped slots in which the oppositely disposed lugs B of the contracted sleeve portion of the male member B are adapted to fit so as to lock the same therein, the member B being partly rotated after the sleeve B? has entered the socket A.

Mounted on the sleeve portion of the female member is a coil spring C which bears against an annular flange of a sleeve D which extends intoI an 'annular groove E formed inthe body of the female member and is normally held outwardly by the spring, said flange having oppositely disposed lugs D( which lit within the slots of the female member and bear against the sleeve portion of the male member so that when the lugs of the male member are forced into the slot, the lugs of the sleeve will be forced past the notches so as to allow the lugs of the member B to be turned into the same whereby the lugs will be forced outwardly in the slots oppositethe notches so that it will, be impossible for the same to be detached without first moving the sleeve inwardly. For preventing the sleeve from being forced offv the female member, we employ, a nut F which works on the extreme threaded end of the sleeve of the female member' and is provided with notches adapt-' turned, the sieeve with the ings will be held in position apposite the notches by the coil spring so as to prevent the same from coming out.

Arranged within the contractedl sleeve portion of the male member is a neck Gr which is provided with an annular shoulder Gr at one end adapted to engage the shoulder formed by the contracted portion of the male member and be securely locked. against the same by a nut H working in the threaded bore of the male member. The other end of the neck G is cut away to form a conical portion adapted to fit against the sides of the socket smoothly, the extreme end ofthe same engaging a rubber washer I which is arranged in an annular seat formed in the lower end of the conical socket of the female member, said washer being locked in position therein by a. nut J working in the threaded bore of the female member. By this arrangement, when the washer becomes worn, it is only necessary to unscrew the nut in order that the washer can be removed and a new one inserted. The conical portion of the neck coincides with the conical lportion of the sleeve of the male member so that when the parts are in a locked position7 a tight joint will be formed between the same and by havingv the rubber washer arranged at the extreme yend an exceedingly efficient water tight oint is formed.

It will be seen that by this construction, the parts are so arranged and connected together that when any one of the same becomes worn, it can be easily and quickly detached and replaced by a new one and by having the nut F of a larger diameter than the members of the coupler it forms abearing for the same when the hose is being dragged.

The shoulder G is provided with grooves in which fit packing rings G2 which engage the smooth bore portion of the member B and form a tight oint.

The operat-ion of coupling the members is f as follows: The nut F being turned so as to bring the notches to register with the slots of the female member, the lugs of the male member are then placed into alinement with the slots and by forcing the members together until the lugs are brought opposite the notches by turning the male member they are forced into the same, it of course being understood that the lugs of the sleeve are forced inwardly by the lugs of the male member and after the lugs have entered the notches, the lugs of the sleeve are forced outwardly by the spring so as to close the mouth of the notches whereby it will be impossible for the members to be detached v without first forcing the lugs of the sleeve inwardly. After this has been performed, the nutv F is screwed up until the sleeve is brought into the proper position, which inretrasa sures the locking of the same so that all danger of the members becoming loose is prevented.

Having thus fully described our invention, what we claim as new and desire to secure by Letters Patent, is

1. In a hose coupling, the combination with a female member provided with a socket -and a sleeve portion having bayonet slots, of a .male member provided with a sleeve portion having lugs adapted to be locked within the bayonet slots, a spring actuated sleeve mounted on the sleeve of the female member carrying lugs working in said slot, a nut for limiting the outward movement of said sleeve, and a. neck carried by the male member fitting Within the socket of the female member.
